JOURNAL FREE ACCESSThe specular gloss and crystal structure orientation of electro-deposited chromium have been studied for deposits prepared at current densities from 10 to 110 A/dm2, and temperatures from 20 to 70°C, using three kinds of chromic acid baths.
a) CrO3 250 g/l, H2SO4 2.5 g/l b) CrO3 250 g/l, H2SO4 1.0 g/l, Na2SiF6 2.5 g/l c) CrO3 600 g/l, H2SO4 3.8 g/l, Sugar 10 g/l
The brightest deposits are characterized by a (111) prefered orientation as had been shown by Yoshida or Hume-Rothery and Wyllie. Diagrams have been constructed showing the effect of temperature and current density on the values of the specular gloss and crystal orientation of the deposit.
In addition to a well known (111) orientation, a (110) and a special (111) orientations are found at higher temperature.View full abstractDownload PDF (595K) -
Measurement of the Mean Height of Gaps between Metal Surfaces in Contact by Volume Method, IShigeru SHIMODA1955 Volume 21 Issue 249 Pages 458-462
Published: November 05, 1955
Released on J-STAGE: February 16, 2010
JOURNAL FREE ACCESSIt is important for the study of contact mechanism to get the true heights of contact gaps. In this paper, volume method to measure those mean heights is described.View full abstractDownload PDF (1079K) -
Wear Process Analysis of G-Series Carbide Tools (Part 2)Hidehiko TAKEYAMA1955 Volume 21 Issue 249 Pages 463-467
Published: November 05, 1955
Released on J-STAGE: February 16, 2010
JOURNAL FREE ACCESSFollowing the previous report (Part I) here the relationship between the shape of wear land and the tool life is discussed. In connexion with this, especially heat sensitive tool materials have the characteristic of selective wear which has something to do with the shape of wear land or tool life.
In order to make the wear process of G-series carbide tools, a comparison with S-series carbide tools by use of the same material cut, FC 27, is made.View full abstractDownload PDF (1141K) -
